Inphi’s 16nm Porrima 100G platform solution represents the industry’s best performance platform that includes field-proven PAM4 DSP technology, Linear TIA and Driver for PAM4 based client optical modules. Built from the same foundation as the 400Gbps 16nm PAM4 DSP announced at OFC 2018 earlier this year, the new 100Gbps variant avails of all the benefits – experience from five generations of DSP development, each of which have been field deployed starting 2016, optical platform expertise and an API based DSP software suite that will achieve quick time to market with the right trade-offs in power and performance. The Porrima 100G platform enables the anticipated fast ramp of 100G DR QSFP optics inside megascale cloud data centers and wireless 5G deployment. Porrima 100G DSP supports all relevant IEEE PCS and KR/KP FEC options for legacy support and backward compatibility with 3.2T and 6.4T switches with 25G NRZ I/O.

“The industry shipped upwards of three million 100Gbps optical modules last year and is expected to double that in 2018, with the largest share of them being four-laser 100Gbps CWDM modules for single mode fiber,” said Dale Murray, Principal Analyst for LightCounting Market Research. “The Inphi 100G Porrima platform will enable single-laser, full-duplex single-mode 100Gbps optical modules that could be more cost effective than the four-laser variants and will also support breakout with 400G-DR4 for dense 100Gbps fabrics.”

“We are very excited to deliver yet another industry first with our latest 100G Porrima platform offering,” said Siddharth Sheth, SVP, Networking Interconnects at Inphi. “The Porrima 100G is ideally suited for both QSFP and SFP module form factors, offering our customers both legacy QSFP support and an upgrade path to higher density 100Gbps with the upcoming 12.8T switches.”

Key attributes and benefits of the new Porrima 100G PAM4 platform:
• Low power consumption for next generation 100Gbps module applications, enabling <3.5W DR/FR optical modules per IEEE standards and MSA
• Also, enables the DR/FR optical modules for legacy 3.2/6.4T switches while offering an effortless upgrade path for 12.8T switches
• Optimally designed DSP and TIA receive chain for power-performance trade-offs
• Enables customers to develop a 100Gbps optical interconnects in a compact form factor for applications with up to 10km
